what are the functions of the respiratory system discuss System:
The respiratory system is the system of organs that allows us to breathe in oxygen and breathe out carbon dioxide. It consists of the nose, throat, windpipe, and lungs. The nose helps to warm and moisturize the air before it enters the lungs. The throat helps to filter out any large particles. The windpipe, or trachea, is a tube that leads from the throat to the lungs. The lungs are a pair of spongy organs that expand and contract as we breathe in and out. They are located in the chest cavity and are surrounded by a thin layer of tissue called pleura.
